Everything about the Pump Organ


What is it?

The pump organ is an American instrument designed in 1864  by Christian Gottlieb Kratzenstein as a free-reed organ more portable than a pipe organ.

Here’s how it looks and sounds

Not to be confused with

You may hear about it with other names like harmonium (a very similar instrument). Pronounced /pʌmpˈɔː.ɡən/, from the and called armonio in Spanish, harmonium in French and harmônio in Portuguese. A person that plays it’s called an organist.

The Keyboard family means that it has a row of keys, buttons, or levers that make the sound when you press them and in another way of classifying its aerophone meaning it makes sound with air vibration.

Materials

Different types of wood for most of the parts like the body, keys, and reeds, anything from hard maple, beech, pine, maple, etc.

Variants

The types are determined by range:

  • Harmonium:  2 1/2 octaves and up.
  • Melodeon: 2 octaves.

You can also find the regular pump organ with a different amount of keys.

Prices

For the regular pump organ, around $100- 1,000 USD, the cheapest we found was a Victorian Gothic Pump Organ in 1:12 Scale and the most expensive was 42 keys Burma teak woods. In the middle, we have something like the Wooden 7-Stopper, 39-Sur, 3 Ballow for $ 480 USD.

In most cases, you will find used instruments that need repairs, you can do repairs yourself if you want, but getting professional help from piano companies is a viable option too.

Weights and sizes

The size goes around 60 x 50 x 25 In (150 x 125 x 60 Cm) and has a weight from 300 lbs (135kg), that’s the size and weight of an upright piano.

Accessories

Here’s a list of a lot of them, but for this one, you won’t get that many, a set of keys for an organ, a pedal, and a piano cleaning kit with at least 1 product specifically for wood are as much as you’re gonna get.

Start playing

We recommend learning to read sheet music to get the basics. We review resources to help you choose how you want to learn. Now that you know how to read them, you need to get some. 
Sheets come in different notations so we recommend checking various versions of the same sheets, searching for “scores” to get all instruments, and even the “song name for [instrument name] to save on translations.

Don’t forget all the details that combined make a big difference like the way you hold it, efficient warmups, positions, and techniques.

Remember,the pump organ is difficult but fast to learn, once you know the technique and the keys, then it is up to your ability alone, it’s also similar to the pipe organ and electric organ, so you can combine those resources to help you learn.
